Check engine light is solid on and did not go off after several trips, although the gas cap is tightly closed.
The manual says take the car to dealer. That car is over 10 years old, has over 80k miles on it and passed emission test a couple of months ago.
Any ideas what else to check besides the gas cap?

Find a friend with an OBD-II scanner and have the engine tell you what the fault is. I've heard auto parts places will do a scan for free.

The most common faults I've had with my cars are EGR issues (bad valve, bad sensor, clogged ports).

After over 60 miles the engine light went off on its own, but I ordered Ancel AD310 scanner from Amazon anyway, just to see what it will find.

The OBD-II scanner showed the P0101 code.

I was not able to attach a picture. Do the moderators here know that even 300KB .JPG picture gives "HTTP Error" when you try to attach it?

Yes, we're aware of a technical glitch with the attachment function (which has nothing to do with file size).

P0101 by itself on a gen1 Rogue usually means a dirty Throttle Body, a bad PCV Valve, dirty or out-of-calibration MAF, or a failing A/F sensor (front O2), probably in that order. However, since the MAF is easiest, first try cleaning it and performing an Idle Air Volume Learn (IAVL).

As the check engine light is off now, after over 60 miles, I will not attempt to fix anything until it comes on again.

I appreciate your response.
I would not like to use third party service for attachments. What is the ETR for this technical issue?

14 yr old rogue here.

Had my share of check engine lights.

Something has to be dirty up in there.

Do what you seem is fit.

The reason because of my problems was because local gas stations was using crappy corn in our fuel.

And years of carbon buildup, dirty insides. Etc.

The govt supporting ethanol was plain dumb especially when there is a plethora of oil domestically that we stopped drilling for and now supporting electric for the future.

Had way better mileage with pure gasoline when I was a young lad many moons ago.

Only lights I get now are the vdc & slip lights turning on occasionally. I just pray they don’t show up.

Others had these lights show up a few years after purchase. So I’m actually happy it took 14 years.

Runs smooth as butter. But if the lights show up, it might sputter during acceleration.

FIXED!

UPDATE:
The engine light was back, so I was thinking about cleaning the MAF sensor and purchased CRC Mass Air Flow Sensor Cleaner.
Before attempting to clean the MAF sensor, I checked the engine air filter chamber and noticed some pieces of leaves and dirt at the bottom.
I used portable vacuum cleaner to clean that, and it also sucked in some broken plastic retainer clips, that I did not expect to find there.
Then I reset the P0101 code using the OBD-II scanner, and since then the engine light is off.
I keep my fingers crossed, but if the engine light comes back, I will clean the MAF sensor and see if that helps.

Thanks a bunch!

Glad your problem is solved.

Ethanol, corn in the gas, actually cleans engines. It’s a very good scrubber. I regularly soak small engine carbs in E85 that are gunked up to clean them.

It just doesn’t sit long like 80’s gas did.

Thank you for the tip, although I do not see how this is related to the topic we are discussing here
Are you suggesting to clean MAF sensor with gasoline?

No. I was replying to an earlier comment in the thread.
